Description

Solar water heater water tank automatic water supply auxiliary water tank

technical field

The utility model relates to an automatic water supply device for a solar water heater water tank.

Background technique

When using a solar water heater, fill the water tank with water at any time according to the water consumption to keep the water level within a certain range. In the past, water filling was done manually, which was inconvenient and sometimes delayed water discharge, which affected the normal operation of the water heater.

Contents of the invention

The purpose of the utility model is to provide a solar water heater water tank automatic water supply auxiliary water tank which can automatically maintain a certain water level.

The technical scheme of the utility model is: comprising a box body, a floating valve, and a water pipe, the upper part of the box body has a water inlet pipe, a floating valve is arranged at the inner end of the water inlet pipe, and a water outlet is arranged at the lower end of the box body, and the outer end passes through the water pipe and Water heater tank connection.

The box body has an insulating layer.

The floating valve includes a floating ball, a valve stem, a valve plug, and a valve port. The valve port is connected to the inner end of the water inlet, the valve plug is located below the valve port, and its lower end is connected to the floating ball below through a vertical valve stem. .

The utility model has the advantages that the water discharge is controlled by the float valve in the auxiliary water tank, and the purpose of automatic water supply and constant water level is realized. Simple structure, reliable performance and easy installation. Water is supplied from the bottom of the water heater tank through the water pipe, without losing the heat in the water heater tank.

Description of drawings

Further description will be given below in conjunction with the accompanying drawings and embodiments.

Fig. 1 is the structural representation of the utility model.

Background technique

Referring to Fig. 1, the utility model comprises box body 1, float valve 2, water pipe 3, and the upper part of box body 1 has water inlet pipe 4, and float valve 2 is arranged at the inner end of this water inlet pipe 4, and water outlet is arranged at the lower end of box body 1 5. Its outer end is connected with the water heater tank 6 through the water pipe 3 . There is an insulating layer in the described casing 1 .

Described floating valve 2 comprises floating ball 21, valve stem 22, valve plug 23, valve port 24, and valve port 24 is connected in described water inlet pipe 4 inner end, and valve plug 23 is positioned at valve port 24 below, and its lower end passes vertical The valve stem 22 is connected with the float 21 below. In order to make the control water level adjustable, the valve rod 22 can be made into an adjustable structure, for example, it is formed by connecting a screw rod with an internally threaded sleeve pipe, and the length of the valve rod 22 can be adjusted by rotating the screw rod.

When the utility model is installed, the casing 1 is fixed on the side of the water heater water tank 6, and the position when the valve opening 24 of the float 21 is closed is consistent with the water level to be controlled in the water tank 6.
